The LT4320 has very robust MOSFET control scheme. If the power source fails, chatters on and off, or is shorted, the controller quickly turns-off the MOSFETS minimizing reverse current transients.

The LT4320's robustness is demonstrated via the dreaded "file test". Since the file (also known as a rasp) has many teeth, lightly scraping the AC power source's output terminal over the file applies power intermittently in rapid succession to the ideal diode circuit. See the following schematic representation of the test setup:

Figure 3. File Test Setup

and, here is the circuit in action!

Here is a guide to the scope waveforms in the video:

As can be seen in the yellow output voltage waveform, throughout the test, the LT4320 ideal diode not only survives but, it continues to full-wave rectify the input.

The LT4320 is designed for DC to 60Hz voltage rectification, while the LT4320-1 is designed for DC to 600Hz voltage rectification. Higher frequencies of operation are possible depending on MOSFET size and operating load current.
